I have an early SR9 with the round mag release. It became very difficult to drop the mag so I tried to smooth it out and only made it worse. Ruger CS sent a replacement however it is the new D shape. They don't make the round ones anymore. They suggested I check out a few sites but no luck...
What is the difference between MKIII models 10101 and 10103? From the Ruger site it looks like blued vs stainless but my stainless model has a recess in the end of the barrel and the blued does not. Just wondering.
